Claims

[Claims for Utility Model Registration] 1. A fixed punch 2 fixed to the press body,
A press machine is equipped with a movable punch 4 that moves toward the fixed punch 2 to press and process the workpiece A, and the movable punch 4 is reciprocatably incorporated into a movable main body 3 that moves for pressing. The movable main body 3 is provided with an adjustment chamber 6 for adjusting cutting pressure that communicates with a supply source of working fluid, and a chamber 6 that is movable in the same direction as the movement direction of the movable punch 4 is provided in the adjustment chamber 6. A ram 7 is provided, and the movable punch 4 is connected to the ram 7, so that the reaction force when the movable punch 4 is pressed can be transmitted to the working fluid in the adjustment chamber 6 via the ram 7. Cutting pressure adjustment device for press machines. 2. The cutting pressure of the press machine according to claim 1, wherein the working fluid is a compressible fluid such as air, and the pressure inside the adjustment chamber 6 is adjusted by a precision pressure reducing valve 9a. Adjustment device.
